I'd really like to have that...

This will break a lot of code, and in a way that will be difficult to
debug. In fact, this is the only point you mention which would be
reason enough for me not to use your modified version; going through
all of my code to check what effect this might have sounds like a
nightmare.
I see the point of having a copying version as well, but why not
implement the copying behaviour as methods and leave indexing as it
is?

Sounds good as well...

I suspect that full behaviour-compatibility with scalars is
impossible, but I am willing to be proven wrong. For example, Python
scalars are immutable, arrays aren't. This also means that rank-0
arrays can't be used as keys in dictionaries.
How do you plan to implement mixed arithmetic with scalars? If the
return value is a rank-0 array, then a single library returning
a rank-0 array somewhere could mess up a program well enough that
debugging becomes a nightmare.

You mean global attributes? That could be the end of universally
usable library modules, supposing that people actually use them.
